Product description

EIFFAGE presents its robotic glove developed in partnership with the Swedish company Bioservo and designed for the demanding environment of the construction sector. This active and versatile exoskeleton, which is entirely flexible, is designed to mechanically accompany the natural force of the hand to reduce the impact of the physical constraints that may be generated by all the manipulations carried out by operators.

Called Ironhand®, it improves performance and well-being at work thanks to a unique technology coupling IoT and Robotics. After two years of development and full-scale tests on Eiffage Group sites, the Ironhand® glove is now distributed and available throughout Europe for all construction trades.

The video presents this glove and the very encouraging results of tests carried out over several months in real working conditions on EIFFAGE's construction sites.

The glove is equipped with 6 sensors: 5 on the last phalanx of each finger of the hand, and the 6th on the palm. The synthetic tendons embedded in the glove's fabric follow the anatomy of each finger. They can develop a force of the order of 4 kg per finger, replacing the force that the operator should have developed.

The Ironhand® glove is versatile in its use. It can be used at any workstation where manual handling is required, more or less frequently: grasping, tightening, holding, gripping, pinching, cutting, clamping, bending, gripping, welding, supporting, pulling, pushing, holding... The glove is connected by a cable, along the arm, to a power unit that can be used for 7 hours continuously and independently by the employee. This mobile device is both portable and lightweight. The glove weighs 20 grams; the motor unit 800 grams. Since it can be used for all tasks where the hand and wrist are heavily stressed, thanks to a control box, the Ironhand® glove can also be customized. Sensors in the glove record the pressure exerted by the hand. The microprocessor integrated in the glove then develops and adjusts the force required to be applied to each finger, thanks to a motor unit located in the back, to reduce the effort by activating synthetic tendons integrated in the glove. The amount of force applied by the synthetic tendons is adjustable by the operator using a remote control unit attached to the shoulder on one of the backpack straps.

Analysis of the data recorded by the bionic glove's microprocessor has shown that the reduction of effort for the operator is systematic, for all the workstations that have been selected to test Ironhand®. The intensity of the effort reduction or compensation varies according to the workstation and the frequency of handling by the operator: from 25% to 86%.

Aims and objectives

Simply relying on existing prevention and protection measures is not enough to achieve a high level of performance in Occupational Health and Safety.

With its Ironhand® glove, EIFFAGE is demonstrating its commitment to testing, experimenting and researching all the innovations that would make it possible to achieve the best possible level of prevention and protection for the health and safety of its employees.
